I have personal experience with limbs weights and let me tell you, that shit is retarded. Sure the physics on limb weights work on paper, more distance from pivot points (hip/shoulder) means more work/torque required to move, but it's the most inefficient way for your body to move weight. The direct weight on the small joints increases risk to joint pain, tendonitis, muscle imbalance, and gait issues. You're working against your anatomy, injuries are inevitable.
Your goal isn't to get the most work out of a certain weight, your goal is to increase calorie expenditure per step. It is in your best interest to use safer alternatives to accomplish this. I encourage you to try rucking—literally just wear a backpack with stuff in it. I assume you're getting your steps by walking to/from work or school, so a backpack shouldn't be too out of place. The human body favors putting weight close to your torso, so using a weighted backpack works with your anatomy. With a well fitted backpack with sternum and hip straps, it will allow you to increase your work per step with minimum risk of injury. It also builds your back, core, and shoulders. Downside is it requires 4x the weight for you to get the same work vs limb weights. Aim for 10-15% of your target, healthy bodyweight. Carry whatever you actually want to bring plus books, water bladder, plates, bags of sand/rice to reach target weight. Try to keep most of the weight in the closest compartment to your body to reduce leverage on your back. Make sure you adjust the backpack so you feel most of the weight on your pelvis, not your shoulders, to allow transfer of work to the legs. Stick to going no faster than a slow jog. Use hills and terrain to increase your work even further. Loose surfaces like sand and dirt absorbs more energy and requires more work to propel off of. The unstable surface also makes your body activate the stabilizer muscles, increasing work.
Good job so far, don't fuck it up by getting injured.
